bus: arm-integrator-lm: Add of_node_put() before return statement
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node, however when control is
transferred from the middle of the loop, as in the case of a return
or break or goto, there is no decrement thus ultimately resulting in
a memory leak.
Fix a potential memory leak in arm-integrator-lm.c by inserting
of_node_put() before a return statement.
Issue found with Coccinelle.
